SHEET-METAL FORMING AND SETTING MACHINE.

Specication of Letters Patent.

To rall whom t may Concern.'

Be it known that I, GInEoN SUNDBACK, a subject of the King of Sweden, residin at Meadville, in the county of Crawfor and State of Pennsylvania, have invented certain new and useful Improvements in Sheet-Metal Forminv and Setting Machines, of which the following is a full, clear, and exact specification.

This invention relates to a machine for forming and setting metal punchings, and has particular reference to a special form of power press with automatic blank feeding means whereby punchings are formed from a strip blank and Set on a carrying element.

The machine illustrated herein is intended for forming the fastener members shown in myy Patent 1,219,881, dated-March 20, 1917, and afiixing them to the corded fabric tape shown therein. The fastener members consist of `separated jaws and an interlocking member having a recess on one side and a head on the other, these respective recesses and heads being arranged on a pair 0f tapes so as to alternately interlock..

The machine of the present invention has for its object to form and set these fastener members on the tape wit?" one handling of the material, and a further object of the invention is to enable the machine'to automatically set these interlocking members in separated groups of .a predetermined num-` ber each, so that the tape can be cut apart to rovide fasteners of desired length.

he present invention is not limited in its broad aspects to the production of the particular fastener members referred to, nor to the setting of such members on tapes, but is of general a plication wherever it is desired to automatically and cheaply form large numbers of like parts, and to set them on a suitable carrier element.

A feature of novelty in the invention resides in the construction whereby the punching is completely separated from the blank and is then immediately replaced therein so that it can be further fed fr the subseuent operations, of shaping and settin or t e latter alone, bythe blank feed wit out applying the setting tools' directly to the y punching.. Owing to the 'necessit of making the fastener Amembers as neai` y alike as possible, in order that they will lock and unlock properly when set on the tapes, it is necessary to have the utmost accuracy in the shaping and setting operations subsequently to the punching out from the blank, and by causing the punching to be replaced in the blank and controlled thereby, it is possible to apply pressure to the punchin through the blank so as tohold the punc iing firmly during the shaping operation, and then by a further side punching operation through the blank, the jaws are firmly set on the carrier element or tape without leaving any tool marks upon the jaw members themselves. After the jaw members are set, the residue of the blank is fed out in one place and the carrier element having the jaw members affixed thereto is fed out in another direction. The avoidance of tool markson the jaw members themselves is of decided advantage, since it chea'pens the subsequent finishing required in the finished fastener.

In carrying out the invention, various novel combinations and sub-combinations in the controlling, feeding, punching, pressing and setting mechanisms have been secured, all of which will be more fully understood in connection with the description of the accompanying drawings, wherein Figure 1 is a side elevation of a machine;

1 represents a metal blank, which is preferably in the form of a fiat strip, and is fed into the machine from the rear toward the front. The machine is applicable to separate blanks as well as to a continuous strip, but in making very small fasteners such as herein shown, which are approximately oneeighth inch long f and one sixteenth inch wide when fastened and applied tothe tape,y it is preferable to emplo a strip. Referring yto Figs. 1 and 4, t e blank 1 enters guide2and passes through feed rolls 3,3. then through guide 9 to the die unit 10, and between the side guide plate 11 (see Figs. 3 and V8).V The guide lates 11 are controlled by wedges 12 (see ig's. 3 and 8). The wedges 12 are operated-through a slide 13 (see Figs. 3 and 4), and cam plates 14 by the punch head Y15, held in the slide 16 (see Figs. 9 and 10) and moved up and down through connecting rod 17 and crank 18 on the main shaft 8. The ,feed rolls 3, 3 are operated by ratchet 4, pawl 5 and connecting rod 6 from eccentric 7 mounted on the main shaft 8 (see Figs. 1 and 2).

22 is the blanking punch which punches out the entire member'and the piece 34 into die 23 (see Figs. 3 and 4). lAs the punch 22 draws out of the die, the lunger2'y carried by plunger holder 25 andl sleeve 26, is actuated by spring 27 to press the punchings back into original lace in the metal blank 1. The piece 34 ig. 19) lies in the` blank between the jaws 35 of the punching. This scrap piece 34 is pushed out of 'the blank 1 by punch 36 (see Fig. 4) into th(` hole 37 in die unit 10. The next step is to press or form the punching in its final form ready to be clam ed on the tape, and this is effected by punc 38 and recess 39 in di(` unit 10 (Figs. 4 and 5).

On the downstroke of slide 16, as the punches are nearing the blank, the cani plates 14 (see Fig. 3) draw the wedges 12 toward the back, ressing the guide plates 11 toward each ot er with theblank 1n between, thus holding the blank firmly inplacc until released by the forward movement of the wedges 12 on the up stroke of slide 16. Figs. 3 and 4 show the position at the mo- 4easy and free movement of the blank.

ment'theclamping movement of the guid.

^ vital importance. At the time of punching.l

the Atwo plates hold the matenial firmly against spreading and distortion either of the punching or of the blank. This enables the subsequent operations on the punching to be cortrolledthrough the blank, and insures such perfect shape of Vthe finished punchings and correct positioning thereof in the dies, as to produce a highly uniform and s minetrical fastener member and product.

hen the guide plates 11 draw tight around the blank 1, they not only bring the blank into a central position over the dies, but force the punchmgs, if they should happen to get out of place, vinto correct position lengthwise of the blank. The guide plates spread apart during the feed and allow alu t also allows the interlocking or projecting end of the fastener punching to lift up out of the recess 39 (see Fig. 4) in die unit 10 after the impression of punch 38.

At this time the blank l, after reaching die unit 10 is confined between die unit 10 on the bottom and stripper plate 21 on th(` top (see Fig. 8).

n order to avoid reliance solely upon spring 27 to lpress the punching back intfv its orlginal p ace in the blank as punch 22 withdraws, a ositive ymovement is provided. Rod 28 in ad' ition to s ring 27 exerts pressure on sleeve 26 thus orcing the punching into its place in the blank. Rod 28 is acted upon through screw 29 iu lever 30 (see Figs.

9 and 10) and connecting links 31, 32 from eccentric 33 on main shaft 8. Upon the return of the punching to its proper place in the blank and with the coperation of the side guides 11, top of die unit 10 and strip er plate 21, the punching can now be fed or ward by the blank feed rolls 3, 3, without any danger of becoming di laced. A displacement at this time wou d cause much by dpunch 38 to form the interlocking recess projection., At this time, it is neces- .sary to hold the blank and punching down onto theface of the die unit 10 and also to hold it against lateral spreading by contraction of the side ides 11. The strippe; plate 21 partly per orms this function, but

\ shaft 50, arm 51, and link 52 to in addition there is provided a yielding presser or floater 4Q (see Figs. 5, 6, 7, 20) which is mounted in stripper late 21 and bears down on the jaws 35 of t e punching, and on theblank 1, by means of springs 41 (see Fig. 4) and plunger 42. This plunger 42 is timed and adjusted to commence pressurc` as soon' as the forward movement of the blank stops, and can be adjusted to exert a,

positive pressure upon the blank and punching by contacting with a lug on punch block 15 when the punches are in their lowest position. Thus the blank and punching are iirml held in position While the transverse y elongated recess and projection are formed by the punch 38 and die recess 39.

When the blank 1 still carrying the fastener member, which is now finished and ready to be pressed on the tape, is again fed forward, the floater or resser 40 yields upwardly so as to permit t e projection of the fastener member to lift out of the die recess 39 so that it can be carried forward into recess 43 (Figs. 3 and 4) ready to be set. To prevent the fastener member punching `from lifting out of the blank 1 altogether, the lift of the ielding presser 40 is limited as shown in ig. 7". Figs. 6 and 6 show the presser 40 at its lowest position and Figs. 7 and 7 show it at its hi hest position.

he finished punching is now carried forward by the next motions of the feed rolls 3, 3 until it reaches the position where Vthe jaws 35 straddle the corded edge of the tape 44 (see Fig. 19). The tape 44 is fed intrmittently u ward and at right angles to the blank fee` through the hole and slot 45 (see Figs. 3 "and 4) in die unit 10. In this position the jaws 35 are clamped around the corded edge of the tape by side tools 46 (see Figs. 3 and 19) which simultaneously pressy toward each other on the outside of theiblank 1, while the formed jaw nember is being held between the top of the die unit 10 and the resilient presser 40 (see4 Figs. 3 and 4). Each of the side tools 46, which set the jaw members on the carrier element, tape, or Stringer, is held in and moved through the slide 47 which is connected at 48 by leverI 49, rock punch block 15 (see Fig. 2). When the clamping movement is completed, the tape feeds up and lifts the jaw member clam ed to its corded edge, out of the residue o `the blank 1, 'the tape and attached jaw member passing through slot 53 in floater 40 (see Fi 5). There now remains of the blank 1 ony the two edges, which are fed through the tubes 54 (see Figs. 3 and 4) and cut into small pieces by knives 55 connected to the i actuating heads 48 of the side tools, the,l

pieces falling down through chute 56.

Incrder to prevent slipping of the feed,

which vents t e tape from lateral displacement 4while passing around the disk 63. Sliding shoe 72 is pressed against the disk 63 by `passageway under the bed of the machine and up through tension 61 (see Figs. 15 and 17 also assing through the hole and slot 45 (see ig. 3) in the die unit 10. The tape then passes `between the sides of Vthe blank 1 where the interlocking members are clamped around the corded edge, and then leads through slot 62 in the punch holder and then around disk 63 (see Figs. 15 and 17). Then the StringerA or tape leads to spool 64 (see Figs. 1 and 2) on which it is wound up by belt 65 driven from the main. shaft.-

The movements of the tape are controlled by the disk 63 on shaft 66. Shaft 66 is driven by ratchet 67 (see' Figs. 17, 11 and 12) through pawl 68, bell crank 69 and pitman 70 connected to crank plate 71 by radially adjustable crank pin 97 mounted on the main shaftS. The grip of'disk 63 on the tape isproduced by the sliding shoe '72 (see Figs. 15, 16 and` 17) which presses they tape against a knurled or rou hened peripheryof disk 63. The grip is a so obtained by pressure of the tape on the lknurled disk 63 produced b the tension 61,

whose function 1s to hold t e tape taut between the die unit 10` `and vthe tape feed control at disk 63. Disk 63 has a groove 73 for the jaw members on the Stringer,

oove serves as a leader and presprings 74, whose tensioni is released by lever 75 in the position shown in Fig. 16. The springs 74 are made of such length as to permit the shoe 72 tobe lifted out of contact with the disk 63, (see Fig. 16) to facilitate the threading or removal of the ta e between the disk and the shoe.

ig. 21 shows the position of the shoe 72 re ativelyto the disk 63. By reason'of the shoe being pointed at theltape entering end, roducing friction between the slanting e ge`76 and the ta e sliding under shoe 72, the tape tends to fo low the direction of edge 76, or to work itself over to the side. Thus the corde'd edge of the tape, with or without metal, is slidin with considerable ressure against the e ges 98 of the shoe 2, and the edges of the groove in disk 63,

thus placing t grip on the tape close to the corded edge. The corded tape is made so that the corded edge is shorter than the free edge, the latter being wavy, so that the corded edge thus takes practically all of the strain of the feed. It is therefore necessary in order to secure even and uniform spacing of the 'aw members, that the tape be. gripped in eeding close to the corded edge. The clamping of thejaw members on the ta e produces some elongation of the corded e ge of the tape.

The slanting edge 76 has the additional function of preventing puckering or doubling up of the tape in front of shoe 72. This is because thepoint of shoe 72 slides over the tape near the corded edge, at a oint where the tape is not only taut but is lield firmly by its attachment to the cord, so that as the tape glides in under the shoe, the edge 76 flattens out any wrinkles in the same manner as the divergent edges of' a Hat iron would do. 4

Instead of the shoe 72, a sli htly conical idler roller having its high ge engaging the corded edge of the tape can be u sed to press the tape against the knurled periphery of disk 63. This idler roller being controlled by springs 74.

T e tape tension 61 (see Figs. 15v and 18) comprises two tension plates 77 having grooves for the cord which provide guiding means as well as friction surface. These plates are mounted loosely on the ends of Jaws 61 which are pivotally connected at 103 and normally pressed apart by spring 197 mounted between screw bushings 79 which can be turned so as to vary the spring pressure at plates 77. The pressure on the )aws is transmitted throughthe screw 78 disposed at about the center of the plates 77,

so that the plates can rock slightly on the4 ends of the screws and adjust t emselves to irre ularities in the tape without aifecting the riction. In order to prevent puckering, the plates 77 at the lower or entering end are tapered or cut away so as to smooth out a. puckered or wrinkled tape in the same manner as above described with respect to edge 76 of shoe 72. The tape tension is not fastened to the machine, but is held in place by the friction of the tape which in its upward motion holds the tension against the lower side of die unit 10. 80 (see Fig. 17) is a brake holding the shaft 66 and tape roll 63 against movement except through ratchet 67.

The throw of pawl 68 Figs. 11 andv 12) which drives the tape eeding shaft 66 through ratchet 67 is made longer than is necessary to feed' the required length of tape for proper spacing. To regulate the spacing, (see Fig. 11) a shield 81 is rovided which prevents the awl 68 from ropping lon the teeth of rat/c et 67 until the desired throw of shaft 66 has been lprovided. The spring 82 pushes the pawl into engagement ,with the teeth as soon as y:the pawl clears the shield 81. The shield 81 is adjustable around shaft 66 so as to control the number of teeth pawl 68 will feed.

The present machine is designed to x a predetermined number of equally spaced Jaw members on a given length of tape, and then to feed` a blank length of tape to enable the fasteners to be cut apart to receive the additional sliding member not shown herein and 'also end stop devices. The -pawl 68 automatically feeds the excess length of tape required for this purpose, through a second pawl 83' (see Figs; 13 and 14) ivoted on p-in 84 and held ainst pin 85 y spring 86.

Pawl 83 is mounted on the friction ratchet 87, mounted between ratchet 67 and shield 81 pawl| 83 is carried around on the frictionv ratchet 87, it reaches the position where pawl 68 at the rear end of its stroke rides over it. At the beginning of the forward movement pawl 68 then catches the secondary pawl 83. The spring 86 (see Fig. 13) yields to the pressure o pawl 68, allowing the secondary pawl 83 to swing until its forward edge eugages the teeth of ratchet 67. The swinging movement being arrested, continued pressure of 41pawl 68 carries with it the sec ondary aw 83 the two ratchets 87 and 67, the sha 66 and the tape. The ratchet 87 is moved by ring 98 (see Fig. 13) through rolls 90 and spring 91. Arm 92 which operates ring 98 is operated by the spring 93 and the pin 94 in clamp 95 attached to the connecting rod 6, and operated by eccentric 7. The stroke on arm 92 is adliustable by the micrometer head 96 in brac et 97 (see Fig. 14) attached.y to the frame of the machine.A The adjustment ranges from a maximum length equal to the throw o'f connecting rod 6 to a very small minimum. Thus the secondary pawl 83, carried around by the friction ratchet 87, is `made to complete a. single revolution during a predetermined number of o erations of the machine according to t e setting of micrometer 96. Then the seconda pawl 83 is eiective, it will be seen that a ong throw will be iven the tape feed, equal to the full stro e of pawl 68.

If not much variation in the lengths of fasteners Jis required, the friction ratchet with secondary p-awl 83 can be dispensed with.- In this case the ratchet 67 is provided with a high tooth 99 (see Fig. 11) which,will project up above the surface of shield 81 so as to be caught by pawl 82 during each revolution of ratchet .67. By changing the throwy of pawl 68, the length of the metal part of may require further finishing 4 means for feeding a carrier, and means -nal the fastenerI can be varied to a limited extent without changing the over-all length including the tape ends. To materially change the length of the fastener the number of teeth in the ratchet 67 can be Varied, and also the diameter of feed disk 63.

The fastener members as affixed to the tape to remove burs, but this can be done after the members are attached to the tape much more cheaply than by additional finishing operations in the machine before the members are pressed on the tape.

While the machine has been described with reference to lthe making of the members from a strip, the novel principles of the invention are applicable to the feeding of separate pieces, and it will be obvious that in applying these broad features of the invention to other machines some of the parts herein described may be modified or omitted entirely without departing from the invention, and all such modifications will be within the scope of the appended claims.
